Abstract
The utility model discloses a novel hydraulic accumulator which comprises a cylinder body, a hydraulic oil cavity, a piston assembly, a front end cover, a gas cavity and an inflation valve assembly. The piston assembly divides the cylinder body into a left part and a right part. The left part of the cylinder body is the hydraulic oil cavity, and the right part of the cylinder body is the gas cavity. The inflation valve assembly is installed at the bottom of the cylinder body. The front end cover is arranged on the surface of the inflation valve assembly and is connected with the cylinder body in a threaded mode. Through the way, the novel hydraulic accumulator is simple in structure, convenient to design, stable in operation and high in energy storage efficiency.
Description
Technical field
The utility model relates to the component of machine field, particularly relates to a kind of novel hydraulic energy storage device.
Background technique
Accumulator is a kind of energy savings device in hydropneumatic system.It is in due course and changes the energy in system into compression energy or potential energy stores, and when system needs, again compression energy or potential energy is changed into to the energy such as hydraulic pressure or air pressure and discharges, and again mends supply system.When the system instantaneous pressure increases, it can absorb the energy of this part.Guarantee that whole system pressure is normal.
The model utility content
The technical problem that the utility model mainly solves is to provide a kind of novel hydraulic energy storage device, simple in structure, and design is convenient, working stability, and energy storage efficiency is high.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of novel hydraulic energy storage device is provided, comprise: cylinder body, hydraulic fluid chamber, piston assembly, front cover, air chamber and gas charging valve assembly, described piston assembly is divided into left and right two-part by cylinder body, the left-hand component of described cylinder body is hydraulic fluid chamber, the right-hand component of described cylinder body is air chamber, the bottom of described cylinder body is equipped with the gas charging valve assembly, described gas charging valve assembly surface is provided with front cover, and described front cover is threaded with cylinder body.
In preferred embodiment of the utility model, described air chamber inside is filled with nitrogen.
In preferred embodiment of the utility model, described cylinder body top has oil inlet hole.
The beneficial effects of the utility model are: a kind of novel hydraulic energy storage device of the utility model, and simple in structure, design is convenient, working stability, energy storage efficiency is high.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of novel hydraulic energy storage device one preferred embodiment of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1, cylinder body, 2, oil inlet hole, 3, hydraulic fluid chamber, 4, piston assembly, 5, front cover, 6, the gas charging valve assembly, 7, air chamber.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, a kind of novel hydraulic energy storage device, comprise: cylinder body 1, hydraulic fluid chamber 3, piston assembly 4, front cover 5, air chamber 7 and gas charging valve assembly 6, described piston assembly 4 is divided into left and right two-part by cylinder body 1, the left-hand component of described cylinder body 1 is hydraulic fluid chamber 3, and the right-hand component of described cylinder body 1 is air chamber 7, and the bottom of described cylinder body 1 is equipped with gas charging valve assembly 6, described gas charging valve assembly 6 surfaces are provided with front cover 5, and described front cover 5 is threaded with cylinder body 1.
In addition, described air chamber 7 inside are filled with nitrogen, for the pressure in adjustments of gas chamber 7, play and fill the effect can and released energy, and nitrogen is lower to the receptance of temperature, affects less.
In addition, described cylinder body 1 top has oil inlet hole 2.
Be different from prior art, a kind of novel hydraulic energy storage device of the utility model, simple in structure, design is convenient, working stability, energy storage efficiency is high.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
